A sophisticated temporary works solution was formulated to allow
for excavation of a deeper basement while avoiding the need to
install flying shores across the 60m wide site.

The Art Deco interiors of the hotel’s famous Titanic Restaurant
and Atlantic Bar and Grill were dismantled and removed for later
reinstatement. Timber and plaster features were carefully recorded
with latex squeezes taken from all profiles.

The use of BIM
technology and 3D modelling for all services and structures
avoided clashes, aided prefabrication and increased productivity
and safety.

The project recorded 2.3 million man hours
worked without a reportable accident during the construction
phase.

The BREEAM ‘Excellent’ development is home to
the largest and most efficient fuel cell in Europe, with
sustainable features also including thermal stores, a photovoltaic
array and grey water recycling.

100% replacement aggregates were used in the concrete mixes and
the development achieved FSC project certification.

The use of a consolidation centre reduced
deliveries by 70%, the team also surpassing a challenging target of
10m3 of waste per 100m2 gross internal floor
area.

The project achieved a local employment rate of
23.5%.

Salvaged kerb stones and other construction
materials unsuitable for reuse were donated to various local
charities for use in community garden projects.

Collaborative BIM
methodologies were adopted at all phases of the project to
de-risk the design, construction and operation of the building and
ensure a fully integrated handover was realised.

“Development Manager Stanhope and Construction Manager Sir
